Abstract: Systems and methods related to UL communications in a wireless network are provided. A UE receives an indication of a plurality of TXOPs for a RACH procedure from a BS. In an embodiment, the UE starts a timer after either successfully transmitting a random access message to the BS or failing to succeed in any of the TXOPs. In another embodiment, the UE starts the timer at a pre-agreed time after one of the TXOPs, regardless of whether the random access message has been successfully transmitted yet or not. In another embodiment, the UE receives as part of a RACH response an indication of whether the RACH response is split into multiple parts. If the UE does not locate an identifier corresponding to the UE in the RACH response, the UE checks for the indication and, if present, listen for the next RACH response identified from the indication.

Abstract: Techniques are described herein for collision handling in uplink transmissions. A user equipment (UE) may have more information to transmit during an uplink transmission than the allocated resources can handle. The UE may identify that an uplink transmission includes a plurality of different channels. The UE may exclude service types or scale the transmit power of service types based on performing a prioritization of the different channels in the uplink transmission. In some cases, the UE may prioritize ultra-reliable low-latency communications (URLLC) service types over enhanced mobile broadband (eMBB) service types. In some cases, the content of the URLLC service types and the content of the eMBB service types may be considered when prioritizing. The UE may be capable of configuring different sets of priority rules based on reliability thresholds and latency thresholds associated with the service types.

Abstract: Methods, systems, and devices for wireless communication are described that provide for a single bit or multiple bit scheduling request (SR). The SR may be transmitted by a user equipment (UE) to a base station and may indicate that the UE has data to be transmitted to the base station. The SR may include an indication of the priority level associated with the data to be transmitted to the base station, which may be based on the data type, logical channel, or numerology associated with the data to be transmitted to the base station.

Abstract: Methods, systems, and devices for wireless communication are described. An access point (AP) may identify a jitter pattern for a wakeup message. A station may listen using a wakeup radio for a wakeup message during wakeup listening periods according to the identified jitter pattern. A station may receive a preamble having a first bandwidth and a wakeup message having a second bandwidth. An AP may transmit an identifier key to a station, and the station may determine a rotating identifier associated with the AP based on the received identifier key. The station may receive a wakeup message from the AP, compare a sender identifier with the rotating identifier, and power on a second radio. A station may also receive a wakeup message that includes an indication of which station are to be activated.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station (BS) may configure a physical downlink control channel (PDCCH) component of a message B (msgB) communication to include a first portion of the signaling information for physical uplink control channel (PUCCH) for hybrid automatic repeat request (HARQ) feedback associated with the msgB communication and the signaling information for HARQ combining of msgB. The BS may configure a physical downlink shared channel (PDSCH) component of the msgB communication to include a second portion of the signaling information for PUCCH and msgB HARQ combining. The distributed mapping for the signaling information to the PDCCH and PDSCH components of msgB can be indicated by system information, RRC signaling, or hard coded in specifications. The BS may transmit the msgB communication to one or more UEs. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may detect, using a low-power receiver of the UE, a low-power synchronization signal (LP-SS) that is associated with a first coverage area that is larger than a second coverage area associated with a legacy synchronization signal block. The UE may monitor, using the low-power receiver, for a low-power wake up signal, based at least in part on the LP-SS, that is associated with a third coverage area that is larger than a fourth coverage area associated with a legacy wake up signal. Numerous other aspects are described.
